ADJUSTABLE BEARING-BOLT.

Application tiled March 30.

T0 all rl1/wm, it may Concern Be it known that I, NEwToN W. LAMBERT, acitizen ofthe United States, and a-resi dent of North Plainfield, in thecounty otl Somerset and State of New Jersey, have invented a certa-innew and useful Improvement in Adjustable Bearing-Bolts, 'ot' which thefollowing is a specification.

The present invention relates to bolts or spindles. i

An object of the present invention isyto` provide a bolt adapted for useas a means' t'or connecting the parts together, and also to provide abearing admitting of the relative movement of the parts.

Another objectY of the present invention 1s to provide. a bearing boltwith cones adjustable. toward and from each other to take up wear. andwith heads which may be adjusted toward and trom each other independentl\Y ot the adjustment ot' the eones to adapt the bolts to variousapplications. i The above, and various other objects and advantages ot'this invention will be in part described, and in part understood, fromthe following detailed description of the pres- Aent preferredembodiment, the same being illustrated in the accompanying drawingwherein Figure 1 is a side elevation of a complete bolt constructedaccording to the present 1nvention.

Fig. '2 is a longitudinal central section taken through the same.

Fig. 3 is a transverse section taken through the bolt on the line 3 5-of Fig. 2,' showing,- one of the cones and thc bushings mounted thereon.

Fig. 4 is an end view ot' the bolt.

Fig.-5 is a side elevation of the bolt` the bushings being removedtherefrom.

Fig. G is a transverse section taken on the line ot' Fig.v Q showing theangular headed end ot' the adjustal'ile cone.

Referring to this drawing. wherein like parts are desigl'iated b ysimilar characters of reftz'ence throughout the several views, 10designates a bearing cone provided with a relativelylong taper, andwhich is provided upon its larger or outer end with a cylindricalbearingportion 11 merging into the cone 10, and which terminates at itsouter extremity in an enlarged preferably angularly faced head 12. i

The smaller end of the-cone 10 terminates in an'y axially extendingshank .13 which Specifrcation of Letters Patent.

is preferably externally screw-,threaded thrmighout its length, and overWhich is threaded a second cone 14 ofsubstantially the sameconfiguration as the cone 10 and merging at its larger end `into acylindrical bearing portion 15 ot' preferably the same diameter as thecylindrical portion 11. The cone 1J: is threaded upon the shank 13 withthe smaller end of the cone 14 extending toward the smaller end of theCone 10, and the cylindrical portion 15 is provided at its outer endwith an eX- ternally threaded portion 16 upon which is threaded anadjustable head 17. The head 17 is preferably in the formV of nutadapted t'or adjustment *overVV the threaded portion 16 toward and fromthe iiXed head 12 to adapt the bolt to various applications. The head 17is locked in adjusted position upon the threaded portion 16 by means ofa lock-nrt 18 which is also threaded upon the portion 16 and adapted tobe jammed up against the head 17.

The cone 14 is provided upon its vouter end with a rei'luced angularlyfaced head'19 which projects bevond the threaded vportion 16, and whichis adapted to receive a suit- Iable tool thereon for turning the cone 14for adjustment toward and from the cone 10. A cone-locking nut 20 isthreaded upon the outer end ot the shank 13 to be jammed against thehead 1.9 to hold the conel 1% in adjusted position. The/outer providedwith a plurality of diametrically extending slots or recesses 21 adaptedto register, one slot at a time, with a transverse ,opening formedthrough the outer end of thev shank 13, .the opening and the slots beingadapted to re- 'ce1 ve a frotter pin 22 or the like therethrough forholding the locking The cones 10 and 14 vided with nut Q0 from turning.are preferably probushings 23 and provided with conical axial-openings'extending therethrough and adapted to receive the cones 10 and 14.therein.' 1`he Ibushings 23 and '2i have upon their outer ends annularoutstanding flanges 25 adapted to confine a suitable number of partstherelwtwcen and to which the bolt ot this invention may be applied.Y

it is of course apparent that the bolt of this invention may be appliedto various VVparts and devices. and that the body of theJ bolt ma)v beused imlcpendentlj' olthe bushings 23 and 24. it' so lesired.,4 Thebushings 2li and 24 mayl be inserted' from opposite and is adaptedVVVends in an eye or sleeve of a member, and the cone 10, with its shank 13may be inserted throughthe bushing 23. and the cone 1-1 then turned upon theA shank 13 to engage in the opposite bushing 24. lt is apparentthat the cone 11 may be advanced into the bushing Q1 sufficiently todraw the cone 1t) into snug engagement within the bushing 23. The conesmay thus be adjusted trom time to time to take up wear between the Conesand the bushings. or between the cones and any other suitable part ormember to which the bolt may be applied. The locking nut 20 is adaptedto be jammed against the outer end of the cone 14 to hold the samesecurely upon the shank 13 when adjusted. An opposite member or part maybe engaged upon the cylindrical portions 11 and 15 of the bolt and heldthereon between the tixed head 12 and the adjustable head 17. Thisadjustable head may be'advarced toward and from the headl 12. an l1thelock nut 18 may then be jammed against' the, head 17 to hold it securelyin adjusted poston.

The cones and bushings are therefore adapted to be adjusted toward andfrom each other. and the heads 12 and 17 are adapted ,to ybeindependently adjl.1sted.to vary the distance therebetween. .1 Thecotter pin securely holds the lock nut 20 upon the shank 13, andprevents the accidental. displacement ot' the parts which are carried bythe shank and the cone 14.

It is of course understood that various changes and moditiczkxtions maybe made `in the details of construction of the above specificallydescribed bearing bolt without departing from the spirit ot' thisinvention. and being restricted only by the scope ot' the followingclaims.
